Alternating ROW colors in a MySQL query

boboli

Hi all....I found a lot of tutorials about the above BUT....I'm a newbie and I would like to combine this with my code:

here is the tutorial code (I found others very similar to this):

$result = mysql_query (SELECT * FROM table);

if ($row = mysql_fetch_array($result)) {
//run the for loop
for ($i = 0; i < count($row); $i++) {
// Set Table Row Color
if ($i % 2) {
echo "<tr bgcolor=B0C4DE>";
} else {
echo "<tr bgcolor=FOF8FF>";
}
// Now display our table cell info
}

?>
<td><? echo $row["whatever"]; ?></td>
</tr>
</table>
<? }
?>

and this is my code where I have a $color variable to assign the correct font color to the belonging "ruolo"

$result = mysql_query("SELECT * FROM giocatori",$db);

<?PHP
echo "<TABLE BORDER=\"1\">\n";
echo "<TR bgcolor=\"lightblue\"><TD>Ruolo</TD><TD>Nomee</TD></TR>\n";
while($myrow = mysql_fetch_array($result))
{
$ID_giocatore = $myrow["ID_giocatore"];
$ruolo = $myrow["ruolo"];
$nome = $myrow["nome"];

if($ruolo < C)
{
$color = "RED";
}

elseif($ruolo < D)
{
$color = "GREEN";
}

elseif($ruolo < P)
{
$color = "BLUE";
}

else
{
$color = "BLACK";
}

echo "<TR><TD>\n";
echo "<font color=$color>$ruolo</font>\n";
echo "</TD>\n";
echo "<TD>\n";
echo "<font color=$color>$nome</font>\n";
echo "</TD>\n";
}
echo "</TABLE>\n";
?>
</BODY>
</HTML>

I tryed to combine the 2 things but I'm not having it working properly.....
will you be so kind to help a poor newbie ???
thanx

How are the ID_giocatore stored in your database? Name a few entrys.

boboli

OK :
ID_giocatore is a tinyINT
ruolo is a varchar that can be P or D or C or A

now I have managed to assign the font color with the "ruolo" RED if P, BLUE if D and so on; I was thinking about alternating the bgcolor of the rows.....

sgoku01

Oké, does it work when you do this:

if($ruolo == 'C') 
{ 
$color = "RED"; 
} 

elseif($ruolo == 'D') 
{ 
$color = "GREEN"; 
} 

elseif($ruolo == 'P') 
{ 
$color = "BLUE"; 
} 

else 
{ 
$color = "BLACK"; 
}

mahendrakalkura

it will work now

quotes make the difference

boboli

That is not a problem, my problem is to alternate the BGCOLOR of the row!!!! not the font color.... 😕 😕 😕

sgoku01

??? The bgcolor of the row??
You're not working at all with the bgcolor of the row...

To change the bgcolor you have to do this:

<tr bgcolor=$color>

????????????????????????????????????????????

I was speaking about this part of the message....
I need to alternate the BGCOLOR of the rows and I wanted to integrate the above code into my own code but I get wrong results....
any idea on the proper way to do it ?????
sorry for the confusion I made.....
ciao

boboli,

in order to set the bgcolor, you have to assign your color variable to the <tr bgcolor="..."> part, not to the font color.
try the following:

$result = mysql_query("SELECT * FROM giocatori",$db);

<?PHP
echo "<TABLE BORDER=\"1\">\n";
echo "<TR bgcolor=\"lightblue\"><TD>Ruolo</TD><TD>Nomee</TD></TR>\n";
while($myrow = mysql_fetch_array($result))
{
$ID_giocatore = $myrow["ID_giocatore"];
$ruolo = $myrow["ruolo"];
$nome = $myrow["nome"];

if($ruolo == 'C')
{
$color = "RED";
}

elseif($ruolo == 'D')
{
$color = "GREEN";
}

elseif($ruolo == 'P')
{
$color = "BLUE";
}

else
{
$color = "BLACK";
}

echo "<TR bgcolor=$color><TD>\n";
echo "<font>$ruolo</font>\n";
echo "</TD>\n";
echo "<TD>\n";
echo "<font>$nome</font>\n";
echo "</TD>\n";
}
echo "</TABLE>\n";
?>
</BODY>
</HTML>

The example you quote gives the row a color based upon wether it is even or uneven. Your code assigns a color based upon a column in your table.

boboli

Let me explain better....I have my page with the $color working properly with the font color and the $ruolo variable.....
BUT I saw a tutorial to alternate the BGCOLOR of the rows with 2 different colors (say lightgrey and lightblue) for the resulting query.....I tryed to combine the code that I found (see my first message) with the code of my page.....well I've been able to have the row in alternate colors but my $color font color is no more working......
may you have a look to the 2 different parts of the code I posted in the very first message and help me putting them together to have the $color working properly and the rows alternating 2 different BGCOLORS ????
thanx

here it is

if you have any prob msg me ok


<?PHP

$my_color_1="#FF0000" 
$my_color_2="#0000FF" 
echo "<TABLE BORDER=\"1\">\n"; 
$result = mysql_query("SELECT * FROM giocatori",$db); 

$i=1;


echo "<TR bgcolor='lightblue'><TD>Ruolo</TD><TD>Nomee</TD></TR>\n"; 
while($myrow = mysql_fetch_array($result)) 
{ 
$ID_giocatore = $myrow["ID_giocatore"]; 
$ruolo = $myrow["ruolo"]; 
$nome = $myrow["nome"]; 

if($ruolo < C) 
{ 
$color = "RED"; 
} 

elseif($ruolo < D) 
{ 
$color = "GREEN"; 
} 

elseif($ruolo < P) 
{ 
$color = "BLUE"; 
} 

else 
{ 
$color = "BLACK"; 
} 
if($i%2==0) {
    $trcolor=$my_color_1;
} else {
    $trcolor=$my_color_2;
}
$i++;

echo "<TR bgcolor='$trcolor'><TD>\n"; 
echo "<font color=$color>$ruolo</font>\n"; 
echo "</TD>\n"; 
echo "<TD>\n"; 
echo "<font color=$color>$nome</font>\n"; 
echo "</TD>\n"; 
}

echo "</TABLE>\n"; 
?> 
</BODY> 
</HTML>
